CLUTCH MECHANISM FOR MACHINES FOR WORKING HIDES.

SPECIFICATION forming part of Letters Patent 110,497,146, dated May 9,1893.

Application filed January 25,1893. Serial No. 459,703. (No model.)

To all whom it may concern.-

Be it known that I, GorTLInB F. TINNEY, of New York, in the county andState of New York, have invented a new and Improved Clutch Mechanism forMachines for Working Hides, of which the following is a full, clear, andexact description.

My invention is an improvement in a class of machines which are adaptedto work or break raw hides, for the purpose of rendering them soft andpliable as required in the process of converting them'into leather. Suchworking or breaking is ordinarily effected by coiling the hides upon ashaft, or drum, and then reversing the motion so as to uncoil them.

I have devised an improved, automatic, reversing machine which isdistinguished by a novel and compact arrangement of cam, gear, andclutch mechanism, the same being connected with the driving shaft anddrum, wherein the hides are temporarily attached, as hereinafterdescribed.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in whichsimilar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a plan view of the improvement With part removed. Fig. 2 isasectional side elevation of the same on the line 2-2 of Fig. 1. Fig. 3is aface view of the cams and Fig. 4 is an inverted plan view of thefastening block for securingthe hides to the drum shaft.

The hides to be treated are attached to the drum, A, which is composedof the shaft, B, journaled in suitable bearings arranged on the frame ofthe machine, and on the said drum shaft are secured the heads 0, O, O

, carrying a series of bars D placed equal distances apart and arrangedin a circle, as is plainly shown in Fig. 2, some of the said bars beingremovable to permit of conveniently placing the leather in the drum.

The drum shaft B is provided on the opposite sides of the middle head 0with recesses B fluted longitudinally and adapted to be filled by ablock B formed on its under side with longitudinally-extending ribs Bcorresponding to the flutings in the recesses B, each block 13 beingalso provided at its ends with lugs 13 secured by set screws or othermeans to the shaft B. The dampened and slightly lubricated hides arefastened at one end by the blocks, B to the drum shaft, on either sideof the head 0', so that theinterior of the drum is completely filledwith the material to be treated, it being understood that the severalhides wind one upon the other in the drum between the shaft B and thebars D. Now, when the drum A is revolved in one direct-ion, the hidesare wound up on the drum shaft B, so that the surfaces of the hides rubone against the other, and when the said shaft is revolved in theopposite direction the hides unwind, again rubbing against one another.

In order to impart motion to the shaft B in opposite directions, thefollowing device is provided: On the ends of the drum shaft B aresecured the gear wheels E and E, of which the former is in mesh with agear wheel F, mounted to rotate loosely on the main driving shaft G,carrying fast and loose pulleys G and G connected by belts with suitablemachinery for imparting a continuous rotary motion to the said maindriving shaft G. The other gear wheel E is in mesh with an intermediategear wheel H, in mesh with a gear wheel H, also mounted to rotateloosely on the main driving shaft G. On the inner faces of the gearwheels F and H are arranged the clutch teeth F and H respectively,adapted to be engaged by corresponding clutch teeth I and Jrespectively, formed on the clutches I andJ respectively, mounted toslide on and to rotate with the main driving shaft G. Springs K and Kpress on the clutches I and 1 respectively, so as to hold the latterwith their clutch teeth in frictional contact with the clutch teeth Fand H on the gear wheels F and H. The clutches I and J are engaged byclutch levers L and L respectively, carrying on their free endsfrictional rollers 11 and L respectively, traveling on camsNand Nrespectively, formed on the faces of gear wheels 0 and 0' respectively,secured on shafts P and P respectively, arranged at right angles to thedrum A. The shaftsP and P are geared together, and for this purpose theshaft P is provided with a pinion P in mesh with a gear-wheel P securedon the other shaft P. On the shaft P is also secured a bevel gear wheelQ, in mesh with a bevel pin ion Q held on one face of a bevel gear wheelQ in mesh with a gear wheel Q secured on the main driving shaft G. Thetwo cams N and N are so arranged that they alternately actuate theclutch levers L and L, so as to move the clutches I and J respectivelyalternately in mesh with the respective clutch teeth F and H on the gearwheels F and H respectively.

The operation is as follows: When the main driving shaft G is rotatedand the several parts are in the position illustrated in Fig. 1, then arotary motion is transmitted to the drum A by the gear wheels H, H andE, as

the clutch J has its teeth J in mesh with the clutch teeth H on the gearwheel H. The other gear wheels E and F rotate loosely as the clutch I isout of mesh with the clutch teeth F on the gear wheel F. The drum A nowWinds up the hides as previously described, so as to bend them and causethe surfaces of the hides to rub one against the other, and as soon asthe drum A has made, say about seven revolutions, then the cams N and Ncause the clutch levers L and L to change their positions, so that theclutch J is thrown out of mesh with the gear wheel H, and the otherclutch Iis thrown in mesh with the gear wheel F. The drum A is nowrotated in an opposite direction, so that the hides unwind and therubbing of the surfaces of the hides again takes place. The drum Arotates about seven times in this direction, until a change in theclutch levers 'L and L again takes place, by means of their cams N andN, it being understood that the latter are continuously rotated, astheir gear wheels 0 and O are in mesh with each other and are drivenfrom the main shaft G, as previously described.

This operation is repeated for the desired length of time, after whichthe machine is stopped, the hides are taken out of the drum and againinserted with the other side up, and the'above described operation isthen repeated; that is, the hides are first wound up on the shaft andthen unwound in the opposite direction, as above described. In otherwords, while the driving shaft rotates constantly in one direction, thedrum reverses itself at the end of every seventh revolution, so that themachine is entirely automatic. It will be observed, that the drivingshaft is placed parallel to and as near the drum as practicable, and yetallow sufficient intervening space for the reversing gear and cammechanism. The cams N, N, are also placed so that the clutch leversco-act with them in the most efficient manner, and without occupyingspace available for other purpose.

Having thus described my invention, I claim as new and desire to secureby-Letters Patent 1. The improved, automatic, reversing ma chine forworking hides, composed of the driving shaft, the drum to whichthe'hides are attached, the two sets of parallel meshing gears F E, andH H E, which operatively connect said shaft and drum, the two clutchesand pivoted clutch levers L L, the two geared cams N N, with whoseperipheries the free ends of said levers work in contact, and gearingarranged intermediately of and connecting the cams and driving shaft, asshown and described.

2. In a machine for Working hides, the combination, with the drum,driving shaft, clutches, and pivoted clutch levers, of the gear wheels 00, having cams, N and N, on their faces, the free ends of said leverscarrying rollers that work on said cams, and gearing which connects suchgeared cams and the driving shaft, as shown and described.
